Our intention is to teach you how to train your first Bayesian neural network, and provide a Bayesian companion to the well known getting started example in TensorFlow. So why do we need Bayesian neural networks? Traditionally neural networks are trained to produce a point estimate of some variable of interest.
For example, we might train a neural network to produce a prediction of a stock P g ditribution at a future point in time using historical data. The limitation of a single point estimate is that it does not provide us with any measure of the uncertainty in this prediction.
Without a measure of the uncertainty we cannot understand how much risk we are taking when we trade. How Bayesian statistics are related to machine learning. How Bayesian neural networks can quantify uncertainties in predictions.
The tutorial requires TensorFlow version 1. At its core, Bayesian statistics is about how we should alter our beliefs in light of new information. Traditional approaches to training neural networks typically produce a point estimate by optimising the weights and biases to minimize a loss function, such as a cross-entropy loss in the case of a classification problem.
In the rest of the tutorial we will show you how to do this using Tensorflow and Edward. Our machine learning model will be a simple soft-max regression, and for this we first need to choose a likelihood function to quantify the probability of the observed data given a set of parameters weights and biases in our case.
We will use a Categorical likelihood function see Chapter 2, Machine Learning: We next set up some placeholder variables in TensorFlow. This follows the same procedure as you would for a standard neural network except that we use Edward to place priors on the weights and biases.
In the code below, we place a normal Gaussian prior on the weights and biases. Create a placeholder to hold the data in minibatches in a TensorFlow graph. Note that the syntax assumes TensorFlow 1.
To tackle this problem we will instead be using Variational Inference VI. A Review for Statisticians by Blei et al. Contruct the q w and q b.
We use a placeholder for the labels in anticipation of the traning data. Initialse the infernce variables inference.
We load up a TensorFlow session and start the iterations. This may take a few minutes We will use an interactive session. InteractiveSession Initialise all the vairables in the session.
Let the training begin. We load the data in minibatches and update the VI infernce using each new batch.MU Grade Distribution Application Thursday, November 15, Term Instructor. When you search on GOOGLE, type in "SA Cell" after the search term and obtain immediate contact details.

When referencing the F distribution, the numerator degrees of freedom are always given first, as switching the order of degrees of freedom changes the distribution (e.g., F .
